A judge has granted defense lawyers representing Frank Caraballo an extra week to prepare for his trial in the killing of a Brattleboro woman.

Earlier this month, Judge Christina Reiss denied a similar request brought by defense lawyers who asked for an extra two months to prepare for the trial on the grounds that they were wading through an influx of new evidence.

In the latest request, filed last week, Caraballo’s attorneys said they received additional audio and video recordings that need to be analyzed before the trial, which was set to start in the second week of September.

After considering the new request, Reiss decided Tuesday to delay the start of the trial until Sept. 16.

Caraballo, 31, of Holyoke, Mass., is charged with killing Melissa Barratt, 30, whose body was found in a wooded area in Dummerston on July 29, 2011.
